The map shows white areas that used to be covered by glaciers. Arrows show directions that glaciers moved. Based on the arrows, which red point was probably closest to the South Pole at the time of Pangaea?

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.

Study the image of this rock. which characteristic best supports its formation from sedimentary processes? it has many layers. it is coarse-grained. its grain shape is round. its texture is non-banded.

Which phase of the cell cycle ensures that identical copies of the dna are made for daughter cells?
